VSDs are considered to be restrictive


VSDs are considered to be restrictive when LV-RV pressure gradient is


[A] < 64 mm Hg
[B] > 64 mm Hg
[C] < 36 mm Hg
[D] > 36 mm Hg



VSDs are considered to be restrictive

  • VSDs are considered to be restrictive –
    • Less than half the size of the aortic root
    • LV-RV pressure gradient is greater than 64 mm Hg
  • Moderately restrictive VSDs are
    • Approximately half the size of the root – with gradients of approximately 36 mm Hg.
  • Larger nonrestrictive defects – LV and RV systolic pressures are equalized.
